| Abstract: | SiC fibers were coated with Ni by electroless plating and heat-treated to ajudst their electromagneticproperties. The technology of chemical plating was studied to obtain SiC fiber with compacted and well-distributed Nicklecoat. The phase transformation of Ni - coated SiC fibers during heating was characterized. And the influnce of preparingcondition on the electromagnetic parameters of the modified SiC absorbent was also discussed. |
